Modelling of Mantle-Crust Migrant Systems: A New Approach to Systems Analysis of Seismic Events

Fluids have a significant impact on seismic processes in the lithosphere and the earth's crust. They can form systems of mantle-crust migrants that rise in a solid plastic medium due to fluid-fracturing. When migrants are formed, the energy accumulated earlier in the parent chambers under the strength barriers is released. The accumulating energy includes the potential energy of lithostatic pressure and the energy of deformation of the strength barrier . The released energy includes the energy of cavity formation in the strength layer and the energy of fluid ascent into the cavity . According to the condition + − − > 0, the remaining mechanical energy is the cause of such seismic events as rock bursts, unstable zones of low longitudinal wave velocities and seismic “nails”.
